On a related note: I run PowerPC Linux on an iBook2. (Current distro is
SuSE 7.3 with kernel 2.4.12.)

The first time I plugged the Jukebox in and loaded usb-storage, it failed
to recognize the device at all, no matter what I did -- so I rebooted into
MacOS X for a while. Subsequently I needed Linux, and happened to reboot
with the Jukebox plugged in. Guess what? Problem goes away, Jukebox shows
up.

Now the one point to note is that the iBook has a DVD/CDRW, and I was manually
loading ide-scsi so I could burn CD's on it. Here's what my /proc/scsi/scsi
currently shows:

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: FUJITSU Model: MHN2200AT Rev: 7257
  Type: Direct-Access ANSI SCSI revision: 02
Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor: TOSHIBA Model: DVD-ROM SD-R2002 Rev: 1B29
  Type: CD-ROM ANSI SCSI revision: 02

One of these SCSI hosts is USB mass storage; the other is IDE-SCSI, and
I have a sneaking suspicion (haven't yet done the neccessary series of reboots
to confirm this) the the order you load them in is significant.

Oh yeah: here's a tip: iTunes 2.0 doesn't correctly write id3 tags on
mp3s when you rip CD's.

However, if you grab id3tool from http://kitsumi.xware.cx/id3tool/, the
(attached) Perl script may be of some use to you. It expects to see
files stored in a directory hierarchy like artist/album/filename.mp3,
and expects to be passed a file's pathname on the command line: it does
some simple munging of pathname components and then uses id3tool to add
id3 tags to a file. This was a quick and dirty one-hour hack, feel free
to play around with and modify it for your own purposes.
